What proportion of precious metals are actually used inside NVIDIA server racks, and which metals are used the most?
Silver sintering technology is indeed used in high-end power devices and some advanced packaging: it is used for die attach, replacing traditional soldering, providing better heat dissipation and reliability. Mainly applied in SiC/GaN power modules, electric vehicle inverters, high-temperature electronics, etc.
However, in NVIDIA's AI GPUs (such as H100, Blackwell GB200 series):
The amount of silver used is very minimal, mainly in silver sintering paste, for internal chip or mod
